EST™ Compression Papers Product Data Sheet Product Description Our portfolio of EST compression papers especially designed to accommodate the cyclical expansion of pouch and prismatic cells experience during normal operation. The EST C30 and EST C310 Papers take advantage of our low biopersistent Superwool ® fibers, combined with a proprietary formulation to control the overall compression forces within targeted ranges. This material is designed to go between either pouch or prismatic cells, depending on their required compression characteristics, to delay propagation in case of thermal runaway. Lithium ion pouch Cell-Cell protection Excellent finished surface Lithium ion prismatic Cell-Cell protection Adhesive capable design Environmental & Health Safety Superwool low biopersistent fibres manufactured by Morgan Advanced Materials are not classified as carcinogenic by IARC or under any national regulations on a global basis. They have no requirements for warning labels under GHS (Globally Harmonised System for the classification and labelling of chemicals). In Europe, Superwool fibres meet the requirements specified under Note Q of European Regulation EC/1272/2008 (on Classification, Labelling and Packaging of substances and mixtures). All Morgan Advanced Materials Superwool low biopersistent fibre products are therefore exonerated from classification and labelling as hazardous in Europe.
